Question

In the given figure ABCD is a parallelogram angle ADE equal to 50 degree and Angle ACE equals equals to angle BED equals to 90 degree the value of angle EAC + angle ABC - 2 angle DAC is

Answer 1

Thank you for asking this question. Here is your answer:

We know that the Angle BED = 90°

And Angle AEC = 45°

Then the Angle EAB = 45°

Angle ABC is equal to 45°

Angle ADE = 50°

And Angle DAC = 40°

Angle EAC+ Angle ABC - 2 Angle DAC =  45° +45°-2×40°

= 90° - 80°

= 10°

So the final answer for this question is 10°
